The house, in the 2500 block of 206 Street, had been vacant for about two years when thieves allegedly struck in late May or early June.
Police were alerted to the incident when a friend went to check on the property and found the entire house ransacked.
One officer described the scene "as if a giant had taken the house, picked it up, shaken it for ten minutes and then put it back down."
Cpl. Holly Marks said there were few items of value left in the woman's home.
Among the items taken was an old King James Version family bible, along with a complete military uniform from the Second World War, bearing a beaver and crown, marked with the words "Royal Westminster Regiment Number 47".
Other items missing include an electric motor from a garden chipper, a three-speed bicycle and a dark mahogany dining room table and four chairs upholstered with a floral pattern.
The thieves also made off with a bookcase with glass doors, two western saddles, a Nightwatcher surveillance camera and more than thirty 78 rpm phonograph records.
The home's electrical wire and power lines were also cut and about 30 metres of cable and ground service wire and all visible copper pipes were taken. A local church has volunteered to clean up the house.
Anyone with information regarding the incident is asked to call Langley RCMP or contact Crimestoppers.
